No, the xntpd that comes with Solaris has authentication off by default.

I think that this is likely the problem. Either the routers do not
forward the multicast packets, or the packets have a small TTL. You
can easily check this by running snoop on the client and looking for 
packets. "snoop 224.0.0.1 port 123" should do it.
